Design an unambiguous PDA for the language BIT defined below: BIT = {w | the k-th bit from left in the string w is a 0 where k is the number of l's in w}. For example, the string 100110 is in BIT since the third bit (shown in bold) is a 0 and k = 3. As another example, 1" is not in BIT for any n. Also 0" E BIT for all n by definition. %3D
